Something else I noticed while actually playing the game: Circus Maximus seems incredibly difficult to build. I think the issue is the scaling of the Hippodrome requirement with map size. I was playing on a Huge map, and I don't think anyone can get to 6 Hippodromes, given that you typically need Horses in a city radius to build a Hippodrome in that city. Am I missing something?
Try subduing a bunch of horses in the beginning of the game and then save them up to spread to new cities you found.
